Description
Technical field
The utility model relates to mechanical equipment installation engineering part, more particularly, relates to a kind of vibration absorber for machines.
Background technique
At present machinery is directly installed on concrete foundation or steel structure mostly, fix by pre-embedded bolt or on-the-spot bolt, between equipment and basis for being rigidly connected.This installation means of fixation has following three drawbacks at least: 1. the setting height(from bottom) of equipment can only regulate by the pad of different-thickness, time-consuming; 2. because the ability of rigid foundation absorption vibration is poor, the vibration of equipment mainly absorbs by connected miscellaneous equipment, easily damages miscellaneous equipment; 3. for horizontal pump, its base material is generally carbon steel, and under Korrosionsmedium environment, base and stone bolt are easily corroded, and causes base to damage in advance with stone bolt and cannot normally dismantle when serious.
But existing damper structure is all more complicated, it is also not too convenient to regulate.In vibration absorber for machines as disclosed in Chinese utility model patent ZL93232933.0, the height of elevating bracket regulates trouble, and is difficult to the installation precision that reaches higher, and rubber mat easily splits away off from base.

Implement vibration absorber for machines of the present utility model, there is following beneficial effect: between bath mat, bulb base, connecting bolt and internal thread connecting piece assembling after without any need for adjusting, the setting height(from bottom) adjustment of equipment realizes by the adjusting nut on stud, regulates very convenient and is easy to realize accurate adjustment.The utility model is simple in structure, easy to adjust, damping property is good.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the utility model vibration absorber for machines;
Fig. 2 is that A-A in Fig. 1 is to sectional view.
Embodiment
Understand for technical characteristics of the present utility model, object and effect being had more clearly, now contrast accompanying drawing and describe embodiment of the present utility model in detail.
As shown in Figure 1 and Figure 2, vibration absorber for machines of the present utility model comprises bath mat 1, bulb base 2, internal thread connecting piece 3 and stud 4.
When installation, first bath mat 1, bulb base 2, internal thread connecting piece 3 are connected by connecting bolt 10.Then the stud supporting with machinery foundations 4 is reliably connected with internal thread connecting piece 3, more successively adjusting nut 5, locking nut 6 and lower gasket 7 is arranged on stud 4.Then the above-mentioned connecting body assembling is through the bolt hole of equipment from machinery foundations below, tightens locking nut 6 after equipment being transferred to required absolute altitude by adjusting nut 5.Finally successively upper gasket 8 and set screw nut 9 are arranged on stud 4 and tighten set screw nut 9.
Further, between bulb base 2 and internal thread connecting piece 3, for sphere is connected, can play the effect of Automatic Levelling.Internal thread connecting piece 3 can rotate on bulb base 2, and the angle of rotation is less than 5 °.
Further, in bath mat 1, be provided with mounting groove, the head of connecting bolt 10 is positioned at mounting groove.Connecting bolt 10 is preferably hexagon socket head cap screw, and spanner easy to use carries out dismounting.
Further, between the head of connecting bolt 10 and bath mat 1, be provided with and connect packing ring 11.
